Taking a ferry from Onomichi, you will reach Mukaishima.About halfway from Mukaishima, you will see Iwashijima on the right hand side as you ride along the seaside.Please follow the blue line with dedication.

Unfortunately, the cycle track runs underneath the road bridge, so you can only see the beautiful scenery only through the fence. However, please be assured. The Innoshima-Ohashi is the only bridge that you can see scenery through the fence.

By the way, as shown below, in Innoshima, there is a beach, called "Shimanami-beach" and a pool where you can swim.I recall that whenever I've been there, I've been up to the top of the water-slide, and I've waited there for about thirty minutes. As I was scared of the height, I was not able to slide down it!Speaking of which, this time whenever crossing a bridge on the Shimanami Kaido, I've been in two minds as to thinking "What a fantastic scenery it is!" and "Man, it's so high!"

The fee is affordable and it is 1,000 yen per day.However, the website is also in Japanese and it seems limited to people who speak Japanese. According to the person in charge of this, replies in English are not available. Why don't you try in Japanese?
